Micro Energy-Water-Hydrogen Nexus: Data-driven Real-time Optimal Operation

no code implementations21 Nov 2023 Mostafa Goodarzi, QiFeng Li

This paper extends a new concept of energy-water-hydrogen (EWH) nexus, which was recently developed as a solution for reducing carbon emissions from the generation side of power systems, to the distribution side.

Economic Viability of the Energy-Water-Hydrogen Nexus for Power System Decarbonization

no code implementations18 Nov 2023 Mostafa Goodarzi, QiFeng Li

This paper aims to evaluate the economic viability of the energy-water-hydrogen (EWH) nexus as a new solution for reducing carbon emissions from power systems.

End-to-End Streaming Video Temporal Action Segmentation with Reinforce Learning

1 code implementation27 Sep 2023 Wujun Wen, Jinrong Zhang, Shenglan Liu, Yunheng Li, QiFeng Li, Lin Feng

The end-to-end SVTAS which regard TAS as an action segment clustering task can expand the application scenarios of TAS; and RL is used to alleviate the problem of inconsistent optimization objective and direction.
